  • This is the collection level record for the N.H. (Doc) Fisher Geoscience Library's Australian geological field notebooks. Digitisation and transcription of these notebooks by a dedicated team of volunteers via the Australian Museum's DigiVol Citizen Science platform is ongoing (subject to annual funding). The Australian field notebooks contain the geological observations recorded by geologists of Geoscience Australia (GA) and its predecessors during fieldwork across the country from the 1930s until paper notebooks were replaced by electronic devices. The intention of this work is to make the content of these unique historical artefacts more widely accessible to researchers and the public. At present, access to the majority of the field notebooks is only available by visiting the N.H. (Doc) Fisher Geoscience Library at Geoscience Australia in Canberra. However, individual records for the Australian notebooks can be found in the Library's online catalogue, at: <a href="https://geoscienceaustralia.intersearch.com.au">https://geoscienceaustralia.intersearch.com.au</a>.

  • This the top-level collection record for all of Geoscience Australia's public vocabularies. The vocabularies are all formulated using the SKOS (Simple Knowledge Organization System) information model and delivered both as machine-readable Resource Description Framework (RDF) data and also as HTML web pages. Each vocabulary is delivered individually as RDF & HTML data and all vocabularies are linked to from both GA's vocabularies index static web page and also from the Australian National Data Service (ANDS)'s Research Vocabularies Australia (RVA) portal. All vocabularies, collections of concepts within vocabularies and individual concepts are identified with URI persistent identifiers of the form: http://pid.geoscience.gov.au/def/voc/ga/{VOCABULARY-KEY}/{COLLECTION-OR-CONCEPT-NAME} This means that you can access all the information about a vocabulary, a collection or a concept directly by entering that URI into your web browser.

  • Digital Elevation Model data record the terrain height variations from the processed point-located data recorded on an airborne geophysical survey. The aircraft altimeter data records the height of the aircraft above the ground and the aircraft GPS records the height of the aircraft above the ellipsoid. Subtracting the two values enables the height of the terrain beneath the aircraft relative to the ellipsoid to be calculated. This ellipsoidal terrain height is corrected for the variation between the ellipsoid and the geoid (the n-value correction) to produce terrain heights relative to sea level.

  • The national standard lexicon of geologic units, including: age, lithology, geologic relationships for all Australian geological units, and a record of their use in literature. Links to Geological Provinces and Geological Maps. The collection is maintained by Geoscience Australia on behalf of the Australian Stratigraphy Commission, a standing committee of the Geological Society of Australia. <b>Value: </b>The lexicon standardises terminology for geologic units, thereby enabling integration of different geologic studies and datasets. <b>Scope: </b>Covers all Australian Territories, including Australia's Antarctic Territories. The database contains over 17,500 current stratigraphic names and over 36,000 variations, most of which are superseded, obsolete, or misspelt versions of the current names. The publicly accessible portion of this collection is made available through the Australian Stratigraphic Units Database (ASUD), the national authority on stratigraphic names in Australia and can be accessed here: <a href="https://pid.geoscience.gov.au/dataset/ga/21884">https://pid.geoscience.gov.au/dataset/ga/21884</a>

  • The BMR Yearbooks followed on from and retained the format of the final BMR Annual Report. The 1977 yearbook did not use that word in its title, which was simply BMR77. Later volumes followed this pattern, but added the subtitle: Yearbook of the Bureau of Mineral Resources, Geology and Geophysics, and in common usage they became known as the BMR (later AGSO) Yearbooks.

  • On behalf of Australia, and in support of the Malaysian accident investigation, the Australian Transport Safety Bureau (ATSB) led search operations for missing Malaysian Airlines flight MH370 in the Southern Indian Ocean. Geoscience Australia provided advice, expertise and support to the ATSB to facilitate marine surveys, which were undertaken to provide a detailed map of the sea floor topography to aid navigation during the underwater search. Prior to the Phase 1 bathymetric survey, very little was known about the sea floor in the MH370 search area, as few marine surveys have taken place in the area. Existing maps of the sea floor were coarse, having been derived from satellites and only providing a general indication of water depth. Before the underwater search for MH370 could begin, it was necessary to accurately map the sea floor to ensure that the search was undertaken safely and effectively. Survey vessels spent months at sea, scanning the sea floor with multibeam sonar and side scan sonar to gather detailed, high-resolution data. This collation of datasets on the National Computational Infrastructure contains the high resolution raw and processed data acquired during Phase 2 of the search for MH370 as received by third party operators. The Phase 2 underwater search data was acquired by multiple vessels, including the Fugro Equator, Fugro Supporter, Fugro Discovery, Havila Harmony, Dong Hai Jiu 101 and Go Phoenix. Surveys were conducted using towed and autonomous underwater vehicles between September 2014 to January 2017, collecting over 121,000 square kilometres of high resolution data in the search area.

  • The Geophysical Data Collection hosted at the National Computational Infrastructure (NCI) contains individual airborne survey lines of geophysical data, including Total Magnetic Intensity, Gamma-ray spectrometry (radiometrics - K, Th, U) and elevation, as well as, ground based Bouguer Gravity. These datasets have been used to create both survey scale and national grids for the geophysical data types. The data were sourced from publicly available government- and company-acquired geophysical surveys in Australia and its surrounding marine area. Other GA Geophysical Data Collections not held at the NCI are discoverable via <a href="https://pid.geoscience.gov.au/dataset/ga/100444">eCat# 100444</a>

  • The Onshore Seismic Data Collection includes regional crustal scale seismic datasets across the Australian Continent collected by Geoscience Australia (GA) and its predecessors, the Bureau of Mineral Resources (BMR) and Australian Geological Survey Organisation (AGSO) in collaboration with the State and Territory Geological Surveys, Australian National Seismic Imaging Resource (ANSIR) ( National Research Facility for Earth Sounding), AuScope Earth Imaging (under the Australian Government's National Collaborative Research Infrastructure Strategy), Universities and other industry and research partners. The collection preserves raw and processed seismic data. The GIS dataset of Onshore Seismic Surveys from 1976 to present (updated May 2019) shows locations of seismic recording stations (the original ecat <a href="https://pid.geoscience.gov.au/dataset/ga/100802">100802</a>). It is generated from a database containing coordinates of all Geoscience Australia's seismic traverses. This Shape file enables users to display seismic lines on a map and contains links to data packages available for free download. < b>Value: </b>Data used to expand the geoscientific understanding of the earth's crustal structure and provide new insights into Australia's onshore energy and mineral potential. This data can be used for the assessment of resource potential. <b>Scope: </b>Primarily targeted regional crustal scale cross-sections (2D) for research purposes. <b> To view the seismic dataset by state use the following URL: </b> https://www.ga.gov.au/about/projects/resources/seismic
